It makes a lot more sense when 7.5 doesn't have to be the constant, I'm not sure why I got hung up on that.

When you build a box with a swapable port, how to you determine internal box volume, as in, what it needs to be once the port is in? I'm going to build a box for the BTL that's 7.5 cubes and want three different ports, 26hz, 34hz, and one for whatever my peak frequency in the vehicle with be. I'm not sure, but wouldn't the different port sizes also affect tuning by changing box volume? I feel like this is really simple and i'm just punching myself in the face here. What am I missing?

Thanks, both of ya Any tips on how to make the external port length look not so funky?

Good enough comparison for me. ^^ Thanks

Just curious about this amp, I found it online, but not many reviews. It's also in the SSA store. Looks sick, but no reviews there either. Anyone heard one, seen one, smelled one, etc. lol.

ohhhhh my goodness. Me too lol, but anything you've heard about them? I haven't heard anything good OR bad yet.

That's just my dogs. They're dorks lol.

Just a short video, my dogs always run upstairs when I turn the woofer on. It's a BTL18d2 on 50w rms. I ended the video, because the satellite speakers fell off the enclosure, they sit on top lol. Nothing much, but shakes a fair bit. Finally got some crossovers to use, and was testing it out this morning. One does not simply run a BTL full range. It's stupid to use it for home audio, but I hate having a $500 paperweight. So take it for what it is.

all Izzie (the dark one) does is sniff the volume knob til I turn it up. She loved my truck. Ever since the day I got her she's slept in front of my stereos lol. Speakerdog Jada is a therapy dog, and is probably just tryna cut loose and go buck wild when she's not at work idk lol My dogs for some reason don't like even a little bass.They just bark and want out. I always thought their hearing was much more sensitive so my pups baffle me.

What I do is take everything completely apart til the problem stops. Then I tear it all down, and put it together one piece at a time, til the problem starts. If it isn't resolved by the first step, now you have a definitive answer as to what's causing it.

Blind suggestion, any use using poly at this power level?

The speaker only does what it's told. Check all else before the woofer.

That's how I got my BTL for dirt cheap, my friend couldn't convince anyone of how awesome it actually was. Lol

Awesome work man

As in, built into the motor, or a particular port design guiding air past the motor?

I'm right, it just boils down to price?Now what about this, Even if it were applied, would there be any appreciable benefits? Extending the thermal rating of the driver. So in competitions where this would be legal and you are limited in cone size theoretically you could then worry about the mechanics of the driver and not the thermal rating. Obviously a driver would need to be designed for the cooling for it to be effective.There are current competition formats that would have something like this banned?

How did they become famous? Lol

I realized the LMS Ultra... The Evil...The Team...The sp4... They have a coil the size of a can of Planters. Holy shit. I held a can of peanuts next to my BTL for two hours today going what the fuck.... Lol and this thing is only a 3" coil? I can't even imagine. That is all.

Well yeah... That's usually the plan lol

post the specs of that box.

and if it's too big... Put a few blocks of wood inside, or brace it lol.

Thanks

Two twelves in a proper box will blow it away, save some money and enjoy
